GTX 550 ti vs GTX 650 ti vs HD 7770 OC

Which one of these would perform better in games such as Call of Duty Black Ops or Battlefield 3 or games in general?
GTX 550 Ti
GTX 650 Ti
or Gigabyte Radeon HD 7770 OC version?

Also I've heard that Radeon is bad for playing games and I've also heard the opposite that radeon is the best and GeForce is bad
What are your opinions and which one of these would perform better? They are also all in about the same price range, just looking for best performance for about the same money. Thanks!

  1. In the same price bracket, you will get about the same performance. Or, at least so close that it really does not matter.
    The GTX650ti might be the strongest, with the 7770 next.

    If you are targeting a specific game or two, look for some benchmark results for those games specifically. It can sometimes make a difference.

    In general, most prefer the drivers from Nvidia, and the amd cards seem to be priced more agressively.

    Don't anguish over minor details, you will get good value for your money from any of them.
  2. yep 650ti is the strongest of the lot and its really power efficient and compact too.

    Its like half the size of my 550ti and outperforms it lol
  3. HD 7850 1GB would outperform all of them for $10 more
  4. The GeForce GTX 550 Ti has a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It features 192 SPUs, 32 TAUs, and 24 Raster Operation Units.
    Compare that to the Radeon HD 7770, which uses a 28 nm design. ATi has clocked the core speed at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.
